Chemical name: Benzeneacetic acid, 4-chloro-.alpha.-(4-chlorophenyl)-.alpha.-hydroxy-, ethyl ester Final regulatory action has been taken for the category: Pesticide Final regulatory action: The chemical is Banned Use or uses prohibited by the final regulatory action: All formulations are banned for use. Pesticide use or uses that remain allowed: None The final regulatory action was based on a risk or hazard evaluation: No Summary of the final regulatory action: It is prohibited to production, use and place on the market all plant protection products containing Chlorobenzilate according to annual adopted list of active ingredients banned for use in plant protection products under the lant Protection Act. The chemical is designated as a PIC chemical. (Regulation on the import and export of certain dangerous chemicals on the Bulgarian territory). The import and use of the chemical for research or laboratory purposes in quantities less than 10 kg are allowed. The reasons for the final regulatory action were relevant to: Human health and environment Summary of known hazards and risks to human health: Routes of exposure: The substance can be absorbed into the body by inhalation, ingestion and dermal contact. Inhalation risk: Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of short-term exposure: The substance is irritating to the eyes and the skin. The substance may cause effects on the central nervous system, resulting in impaired functions. Chlorobenzilate has a slight tendency to accumulate in fatty tissues. Expected effect of the final regulatory action in relation to human health: Decrease of hazards and risks to human health. Summary of known hazards and risks to the environment: Chlorobenzilate is not expected to bioconcentrate in aquatic organisms. Its LC50 is 0.7 mg/l for 95 hours in rainbow trout. Chlorobenzilate is non-toxic to birds, honey bees and beneficial insects. Because Chlorobenzilate is practically insoluble in water and it adsorbs strongly to soil particles (Koc=1,065) in the upper soil layers, it is expected to exhibit low mobility in soils, and to therefore be unlikely to leach to groundwater. Its soil half-life in fine sandy soils was 1.5 to 5 weeks after application of 0.5-1.0 ppm, with the removal probably due to microbial degradation. Due to its strong adsorption to soil particles and low vapour pressure, chlorobenzilate is not expected to volatilize from soil surfaces. Chlorobenzilate adsorbs to sediment and suspended particulate material in water. It is not expected to volatilize or to bioconcentrate in aquatic organisms, but may be subject to biodegradation. Chlorobenzilate is fairly persistent on plant foliage and may be phytotoxic, or poisonous, to some plants. Expected effect of the final regulatory action in relation to the environment: To avoid and reduce exposure, hazards and risks of the chemical to the environment. Date of entry into force of the final regulatory action: 01/01/2004 |
